P vention is to provide a simply constructed, The wheel felloe 1carries the customary easily assembled, inexpensive and durable metallicrim 2 on which is mounted the outer chain which can be readily fastenedon or casing or tire 3 which contains the inflated 5 removed from thetire as occasion demands. rubber tube 4;.

The chains are located so that the links nthth abQVe more important objects in of the one chain are directlyopposite those view, the invention consists essentially in the of theother whereby the links appear in arrangement and construction of partsherepairs, One on each side of the tire.

The attachin ends j idmWmgS hke of refer 13 of the bars are riveted as indicated at enceindicate corresponding parts in the sevto the overlying ends of the01.033 bars {3 A .1 45 em} figuresthe rivets passing through the opencentres Ihave not herein considered it necessary to f h k In this 5 theGregg bars as how an entire wheel nor the entire chain, i well as thefingers are firmly fastened to the ing eufliclent the P p of time sidechains. It will be observed that there scription to understand that mydevice cm is a set of fingers at each side of the casing 1m tirelysurrounds the outer casing of the and that the tipsof the fingers arespaced from and oppose the flanged sides of the rim 2 with the resultthat any undue rotary movement of the cross bars in respect to thecasing will be resisted by the tips of the fingers coming in contactwith the side flange of the rim.

The chains will be shortened or lengthened by removing or undoing linksand so can be accommodated to the tire.

The free ends of the chains are pulled tight and connected together byutilizing a special lever for each chain, one of the levers being shownin Figure Here it will be observed that the said lever 16. is formedfrom predetermined length of bar bentbackwardly on itself to providelong and short ends. The long end of the bar terminates in a hook 17facing in one direction and the short end oi the bar terminates in ahook 18 facing in the opposite direction. At the point where the bar isbent, it is provided with a T-shapcd slot 19.

One end of each chain carries a locking clip 20 which is made fromspring wire bent in the manner best shown in Figure l where it will heobserved that the clip is retained on the chain and has U-shaped ends 21and hen it isdesired to fasten the ends of the chain together, the leverin cachinstance caught on the ends oi the chain in the manner shown inFigure iand then the lower end thereof is rotated in a counter clockwisedirection to pass the slotted end of the lever towards the locking clipor keeper. The U-shaped portions of the keeper are adapted to be sprungthrough the contracted or narrow portion of the slot 19 and havingpassed through this to spring apart and catch in the endsof the largerportion of the slot.

Vhilst I have described a specific lever and keeper arrangement fordrawing up and fastening the ends of'the chains, it will he readilyunderstood I do notdesire to be limited to the precise arrangement shownas any other suitable device could be used. It will be observed thatwhen finally fastened, the lovers are to the inner sides otthe chains sothat they are not in any way contacting with the road surface.

A chain of this nature gives a relatively large wearing surface andpresents a considerable area to the road thereby materially preventingsinking or miring. The flanges insure of effective traction and thecorrugations of the flanges avoid skidding. Further it is not necessaryto cut links to shorten or lengthen the chains as it is simply amatterof inserting or removing one or more of the links as beforementioned. Also the fingers engaging with the rim prevent undue rotationof the cross bars in respect tothe tire.

Vlrat I claim as my invention is:

The combination with a rim and tire mounted thereon, of side chainslocated at opposite sides of the tire and formed from a series ofdetachably connected flat links p0- sitioned substantially at rightangles to the tire, means for tightening and fastening the ends of thechains, cross bars bent to span the tread side of the tire and havingoutstanding ends permanently riveted to selected links of the chains andstop fingers permanently secured to the side chains and opposing the rimand adapted by contact with the rim to arrest undue rotation of the barsin respect-to the tire.
